This is an interesting product from the aforementioned Luxman;
The M-200 is designed to be portable and completely compatible with fresh new audio source components and high performance audio applications coming to market, such as computer music sources. What’s more, its rated output is 25W+25W (8Ω), concentrating on the ultimate sound quality rather than quantity.
Instead of rigidly adhering to the traditional audio forms, the M-200 introduces modern high performance parts and assemblies that will meet the requirements of the most demanding audiophile. This Luxman fully featured new product provides both beginners and hi-fi experts with a wide variety of audio solutions.
As a high quality stereo amplifier, M-200 can be used with various audio components, such as the USB D/A converter DA-200 with high-grade built-in potentiometers and the E-200 phono stage. The M-200 has both fixed and variable inputs, so you can be used with an external preamplifier if you wish.
Furthermore, in BTL mode M-200 can work as a mono amplifier with 70W (8Ω) output to achieve greater driving forces for large-caliber speakers. You can also activate/deactivate its built-in pre-amplifier and add discrete pre-amplification if you prefer to do so, making the M-200 highly versatile in a variety of applications.
The front panel display is able to process and track reproduced signals in real-time. It is also equipped with a digital power meter (backlighting can be switched off), which can be switched between power Output, Speaker Impedance, Hold Time and other digital settings. All the above provide you a visual and informative feast while enjoying the music.
